BLANK FOR PAPER BOXES.

SPECIFICATION forming part of Letters Patent N0. 634,507, dated Octoberl0, 1899. Applica-tion filed May S, 1899. Serial No. 715,999. (Nomodel.)

To CLZZ whom t may concern:

Be it known that I, HARRY B. SMITH, a citizen of the UnitedStates,residing at New York, (Brooklyn,) in the county of Kings andState of New York, have invented certain new and useful Improvements inBlanks for Paper Boxes; and I dohereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appert-ains to make and use thesame.

My present invention relates to certain new and useful improvements inbox-blanks, and more particularly to blanks for forming paper boxes.

It is the prime object of the invention to provide an extremely cheapandeasily-constructed blank for forming paper boxes having curved orrounded 4corners, the bottom, ends, and sides of the box being formedfrom a single blank, and the Wings forming said ends and sides beingconstructed in such manner as to form when folded up into position asmooth unbroken surface around the entire outer circumference of thebox, no overlapping parts whatever vbeing present in the structure,which is one of the essential and distinguishing features of theinvention.

The demand for a paper box having curved or rounded corners 'is verygreat at the present time; but as heretofore constructed it wasimpossible to obtain such a box at a price low enough to enable itsgeneral use in connecf tion with articles sold at a nominal price.Furthermore, boxes now upon the Vmarket having rounded corners, so faras I am aware, either have crimps or folds at the corners or are formedwith overlappingportions or edges,

Which render such corners unevencumber some, or bulky, and otherwisedetract gener# ally from the neatness of the box.

Briefly stated, my. invention comprises a box-blank made from paper orcard board and consisting of a body portion of any desired shape havingits corners rounded orcurved and provided with side and end Wings orflaps `which have the opposite ends thereofcut off or removed to such adegree or extent as that when vfolded up to form a box the adjacentedges of'said Wings or fia-ps will abut against each other to form aclose t, but will not overlap each other, thus producing a smoothandcontinuous unbroken surface around' the outer circumference of thebox.

In order to enable others to construct boxblanks and boxes in accordancewith my invention, I will proceed to describe the same in detail,reference being had for this purpose to the accompanying drawings,wherein- Figure l is a plan view of one of my improved box-blanks. Fig.2 is a perspective view of a box formed from one of my blanks. Fig. 3 isa transverse sectional view of the blank, taken on the line of Fig. 1.

Referring now to the drawings, the reference-numeral l designates thebody of the blank, which in the present instance is shownl as beingrectangular in shape; but I wish it understood that I do not confinemyself to any particular shape of blank, for obviously the shape andgeneral outline of the blankpmay be varied at will without'departingfrom the true spirit of the invention, the novel features of which Iwill now describe.

The corners ofthe blank l are rounded or curved, as at 2, and the sidesand ends of the blank are provided with integral Wings or flaps 3 3 and4c 4, respectively, the body of the blank being scored, cut, or creasedalong the lines 5 5 and 6 6, where the said ends and side wings or flapsjoin the said body of the blank, to facilitate the upward bending ofsaid wings or iiaps during the formation of the box. The opposite freeends 7 and S of the side and end wings, respectively, are cut off, sothat the maximum length of each Wing will be slightly less than thecorresponding Width and length, respectively, of the sides and ends ofthe body portion of the blank, whereby when the said wings are foldedupin the position shown in Fig. 2 to form the box and the free ends 7 and8 of said wings are bent around the curved or rounded corners 2 theadjacent edges of the free ends of said wings will just meet and abutagainst each other to form a .close t, but will not overlap, and this Iconsider as the important and novel feature of the invention. After theWings have been folded up in position to form the box they can beretained in such position in any suitable manner, as by metalcorner-clips, short strips of paper pasted or glued to the corners, orby a surrounding strip of covering-paper, which `Wi`l-lbe pastedentirely around. the outer circumference of the box, and owing to thefact that a clean flush joint is formed at the rounded corners, nooverlapping or crimped parts being present, a smooth unbroken surface isthus provided which adds greatly to the neatness and attractiveness ofthe box.

As heretofore stated, I do not wish to be understood as limiting myselfto any particular form or shape of blank, for obviously the lgeneralshape and configuration of the blank may vary to suit the demandsWithout departing from the spirit of my invention, the essential featureof which is to provide a box with rounded corners and a continuoussmooth outer circumference entirely free from projections orundulations, such as are usually present in boxes having crimped oroverlapping portions at the corners.

lfVhat I claim, and desire to secure by Letters Patent, is-

l. A paper-box blank formed from a single sheet, comprising a bodyportion having rounded corners and integral side and end wings, themaximum length of said Wings being slightly less than the maximum lengthof the sides and ends respectively of the body portion of the blank, sothat When said wings end wings, With lines of scoring or creasing 35 at'the points of connection between the Wings and body ofthe blank, themaximum length of said Wings being slightly less than the maximum lengthof the sides and ends respectively of the body portion of the blank, so4o that when said wings are folded upward into position for theformation of the box, the adjacent edges of said side and end Wings willabut to form a close joint but will not overlap.

In testimony whereof I affix my signature 45 in presence of twowitnesses.

HARRY B. SMITH.
